Contrary to popular belief, the bulk of "Hawkmen" does NOT take place in February! The calendar in Indy's bunk is the tell-tale clue because it's clearly March (the previous month ends on the 28th). His assignment is for '2 weeks' and his last mission is on the 13th, which means he probably arrived on 27 Feb. Notice that the direction of Indy's pencil strokes seem to indicate this precisely.
